I’m trying to understand Pagespeed better, and want to ask if it’s working properly for our domain?
We have a WordPress multisite. The images on the pages load with normal URLs the first time, i.e.:
Then in subsequent re-loads of the page, the URLs change to:
This new code functions, but it’s not pretty. And one of the major problems I’m noticing is that when I swap out the image for one with the same name, the cached version is still the one that appears.
So my question is: is this how pagespeed is supposed to function, or is something funky with my WP theme? Do I have any control over the caching, and can I refresh the cache when I need to make a change to the images that are loaded?
